Good question. We all know that telling lies is normally never good. A habitual liar I would say has a problem. I never tell lies. I was brought up , and raised to allways tell the truth.
I would say that being a liar would be and unethical choice for an individual. I had a cousin who was a constant liar, and a thief, and went to prison. I considered him to be a real screw up.
I am not a psychologist, or psychiatrist, but I was a police officer, and I think that both behaviors are terrible ones, and that a lack of ethics might just lead to bad behaviors.
Would lying lead to stealing ? Excellent question. I would not want a liar in my home, or protecting my wallet, or purse if I had to trust one. I do not trust liars.
Bad behaviors can lead to other bad behaviors in my opinion. This is why it is so important for parents, or leaders , or teachers with good ethics to explain that as good citizens we should always conduct ourselves in proper ethical ways.
I think that one may not lead to the other, but one bad behavior like lying seems as if it would make stealing easier to try.
Stealing is a terrible thing. I have always considered stealing and act of low class predators. They may , or may not be low class predators, but I feel like they are because it hurts when something you cherish is stolen.
And one of the worst crimes of all involves stealing from sick, or elderly people who cannot protect themselves, or their personal assets. Stealing from someone who is vulnerable, ill , or sick, or even dying is a terrible wretched thing to do.
It is very important that parents, teachers, educators, and important officials to take time out to teach children, and young adults not to ever steal, and to never lie. Teach children to do the right things in life. Without guidance children, and young adults are left on their own to learn bad habits.
There is nothing cool about being a liar , or a thief. Both acts are degrading to one's self.
I hope what I have said makes some since. I am not perfect, and do not know everything.
God Bless You
